Description

The thimble connector

Technical field

The utility model relates to a kind of thimble connector, is meant especially about a kind of to have lasting stable transfer effect and a cheaper thimble connector of cost.

Background technology

Nowadays Information technology fast development, digital product miscellaneous comes out one after another, accepted by the modern and be extensive use of such as the portable equipment of digital camera (viditalvideo camera), digital camera (vidital still camera), mobile phone (mobile phone) and the very multiple class of analog thereof, it is battery that these type of carry-along equipment great majority provide the source of power supply, therefore battery also strides forward towards the direction that recirculation is used, and makes the rechargeable type battery become the battery product that nowadays is widely used most.

The structure of the employed thimble connector of conventional batteries charger comprises following member, one sleeve, a cylindric thimble and an elastomer are formed jointly, this sleeve has the accommodation space of the hollow of a bottom lock, this accommodation space forms a port, this cylindric thimble is placed in the sleeve, and this thimble inside has room in, described in room be used for installing elastomer, make thimble can borrow elastomeric elastic force in the accommodation space of sleeve, to slide up and down, and stretch out in outside the port.In use, thimble can be subjected to the strength that battery compresses downwards, makes the thimble inclination and touches sleeve, to reach the state of electrical transmission.

But above-mentioned traditional thimble-type connector, because sleeve is necessary for metal material, and thimble touches the state that sleeve just can reach electrical transmission, yet the sleeve of metal material not only cost is higher, and weight is heavier, so do not meet the light and handy trend of electronic product now, and, this sleeve has only a port, make when electroplating activity, remaining bubble is attached to the inner wall surface and the lower surface of accommodation space, cause and electroplate situation inhomogeneous or that be not electroplated onto, therefore the flaw and the defective of electric connection aspect have occurred, and then made the time, but often found to have electrical conduction problem not good or poor electrical contact to produce as battery supplied electric energy contact electric action.

Therefore, be necessary the sleeve of traditional thimble-type connector itself and the contact stabilization of sleeve and thimble are improved, to overcome above-mentioned defective.

Summary of the invention

The purpose of this utility model is to provide a kind of thimble connector, through improvement of the present utility model, makes the cost of thimble connector lower, weight is lighter.

The purpose of this utility model is to provide a kind of thimble connector, through improvement of the present utility model, makes the thimble connector stable, smooth and easy more when electrically transmitting.

The utility model is a kind of thimble connector, it comprises a sleeve, one extrusome, one elastomer and a bottom plug, wherein, sleeve is a plastic material, this extrusome is arranged in the accommodation space of sleeve, this extrusome inside has room in, room is in order to ccontaining this elastomer in being somebody's turn to do, described elastomeric electroplating surface gold plating bath arranged, the wall of the interior room of this elastomer outside and extrusome forms lasting contact condition, and described bottom plug plugs in the accommodation space bottom of sleeve and with elastomer and forms conducting, and the bottom of bottom plug is welded on the circuit board, continue smooth and easy stable when therefore, making transmission.

The utlity model has following beneficial effect: through improvement of the present utility model, make the cost of thimble connector lower, weight is lighter.Through improvement of the present utility model, make the thimble connector stable, smooth and easy more when electrically transmitting.

Embodiment

Execution mode of the present utility model below is described.

At first please refer to Fig. 1 to shown in Figure 4, be respectively the utility model execution mode three-dimensional combination figure, three-dimensional exploded view, analyse and observe constitutional diagram and sectional exploded view.Main composition assembly of the present utility model comprises sleeve 10, extrusome 20, elastomer 30 and bottom plug 40.

Sleeve 10 is made by the insulation material, it is a column type, this sleeve 10 have one by the top be through to the bottom accommodation space 11, make this sleeve 10 be formed with upper shed 12 and under shed 13, described accommodation space 11 has first inwall 111, second inwall 112 and the 3rd inwall 113 of different inner diameters, and this first inwall 111, second inwall 112 and the 3rd inwall 113 down become big gradually by last.Because this sleeve 10 is the insulation material, so the weight of this sleeve 10 will be more light and handy, and the manufacturing cost of sleeve 10 relatively also can be comparatively cheap.

Extrusome 20 is made by metal material, it is arranged at accommodation space 11 inside of sleeve 10, and can slide up and down in second inwall, 112 inside, the top of this extrusome 20 can protrude in the upper shed 12 of this sleeve 10, this extrusome 20 has a downward opening interior room 21, the bottom of this extrusome 20 has the bigger base of an external diameter 22, makes the top of extrusome 20 stretch out in sleeve 10 when outer, and second inwall, 112 tops that terminate in the accommodation space 11 are supported at the top of this base 22.

Elastomer 30 is placed in the inside of the interior room 21 of extrusome 20, and this elastomer 30 is made by metal material, and is coated with gold plating bath in the surface electrical of elastomer 30, significantly to promote the electric conductivity of elastomer 30.

Bottom plug 40 is made by metal material, it plugs on the 3rd inwall 113 of accommodation space 11 bottoms of sleeve 10, the bottom of bottom plug 40 protrudes under shed 13, the end face central authorities of this bottom plug 40 have a salient point 41, elastomer 30 can be sheathed on the salient point 41 of this bottom plug 40, to avoid elastomer 30 off normals, form conductings with seasonal this elastomer 30 with bottom plug 40 and contact, and described bottom plug 40 is welded on the circuit board (not icon).

Therefore, this elastomer 30 is sheathed on the salient point 41 of bottom plug 40, and the outside of this elastomer 30 contacts with the internal face of extrusome 20, make this extrusome 20, elastomer 30 and bottom plug 40 all present lasting conducting state, so do not have the situation generation that loose contact or transmission have some setbacks, in addition, this sleeve 10 is a plastic material, so can reduce manufacturing cost and whole weight.And this elastomer 30 is electroplate with the electroplate liquid of good conductivity owing to appearance, and then makes laser propagation effect better.

Comprehensively above-mentioned, the utility model has really met the patent requirement of novelty, creativeness and practicality, so propose patent application in accordance with the law.The above, it only is the utility model execution mode, be not to be used for limiting practical range of the present utility model, so all equalizations of being done according to the described shape of the utility model claim, structure, feature and spirit change and modify, and all should be included in the claim of the present utility model.
